COAL-CI-IUTE AND WINDOW-GUARD.

Specification of Letters Patent.

Patented June 12, 1917.

Application filed November 17, 1916. Serial No. 131,972.

To all whom it may concern:

Be it known that 1, JOHN R. Roscon, a citizen of the United States, residing at Fort Dodge, in the county of Webster and State of Iowa, have invented certain new and useful Improvements in Coal-Chutes and Window-Guards, of which the following is a specification.

The invention has for an object to give a simple and efficient construction of device adapted to enable the introduction of coal or other material through a window or port hole without damage to the material of the structure in which the opening is formed, particularly applicable to use in storing coal in cellars, where it is introduced through a window in the front of the building.

It is an important object to give a device which will not require to be fastened to the building, and which, while serving as a guard to protect brick Work and window framing from engagement by coal being introduced therethrough, yet requires a minimum of material for the purpose, a chute support being so constructed and arranged that it serves the two functions of supporting a chute properly in the window, and affording a protective means before the buildmg.

It is a very important object of the invention to give a desirable construction of chute mounting whereby a chute may be readily introduced in any ordinary window, and adjusted at various angles, with respect to the vertical, and also directed to one side or the other within a window opening, as desired. A further important aim is to give a construction of chute and support which may be easily folded into very compact form, enabling it to be carried conveniently upon a wagon or otherwise stored in a small space. A particular purpose is to provide a desirable means for adjusting the chute at various angles, and to support it readily for convenient folding against the supporting frame.

Additional objects, advantages and features of invention will appear, in connection with the showing herein of certain possible constructional embodiments of the invention, the drawings showing in Figure 1 a front elevation of one form of my invention in use,

There is illustrated a portion 10 of a building, having a window opening 11 therein, provided with any usual window frame 12, and closure which in the present instance is shown of the casement type, open. The window has at its lower part the usual sill 13, which may be utilized, in one form of the device to support the guard frame and chute.

My invention in the present instance includes a guard frame and support consisting of two stiles 15, between which there are engaged a suitable number of rails 16, 17, and 18 to hold the stiles in rigid relation. The rail 16 is engaged between the stiles a short distance above their lower ends, while the rail 17 is disposed thereacross at a suitable distance above the first rail to give an ample opening for the adjustment of the chute, and clearance thereover for passage of coal as maybe required. The uppermost rail 18 is located closely adjacent the upper ends of the stiles, and between the last two rails mentioned a suitable panel 19 of any desired material is incorporated, upon which advertising may be printed, if desired. In the stiles, immediately below the middle rail 17, there are formed openings 20, in which there are revolubly engaged coaxial ends 21 of a crank hanger 22, formed from a suitable bar of metal bent centrally to form the two cranks 23, connected by the supporting bar 24. The cranks are located closely adjacent the stiles, leaving a considerable space therebetween. Engaged upon the bar 245, there is a chute 25, which may be of any familiar construction, preferably of a width considerably less than the distance between the cranks 23, so that it may have a suflicient range of lateral adjustment therebetween. The chute 25 is secured to the bar 2 1 by means of a swiveled eye piece 26, mounted in any desired manner on the bottom of the thereinto a distance.

chute, a short distance from its upper end and medially thereof. In the present instance, in Fig. 5 there is shown a plate 27 secured to the bottom of the chute, having a central offset portion apertured and receiving the neck 28 of the eye piece revolubly therein, this neck having an enlargement 29 at its outer part beneath the plate 27. The plate 27 may be riveted or otherwise secured to the under side of the chute. In Fig. 5 there is shown a method of mounting the chute upon the bar 24, consisting in forming an ovate eye member 30-by suitably bending a plain strip of metal of suitable thickness, to form the eye, and providing end portions 31 extending outwardly therefrom, which may be riveted to the bottom of the chute, indicated at 32. The major axis of the ovate opening in this eye piece extends longitudinally of the chute, so that the latter may be readily oscillated late-rally upon the bar 24 without diiiiculty.

In Fig. '6 the bearing is shown as a casting, with suitable flanges secured to the bottom of the chute, and in one side a set screw 33 is engaged through the eye portion 34, to hold the chute secured upon the bar 24 in various positions. In Fig. 7 a further construction is shown in which the bearing consists of an eye bolt 35, the shank of which is engaged slidably in a suitable plate 37, which may comprise the bottom of the chute if desired, the slot 36 being of a length to permit the eye of the bolt 35 to move upwardly Engaged on the end of the shank of the bolt 35 there is a suitable nut 38, by which the bolt may be drawn upwardly to bear the bar 24 against the un der side of the chute with such force as to hold the chute in various adjusted positions on the bar.

Upon the under side of the chute 25 as shown in Figs. 1 to 4 inclusive, there is a ratchet toothed rack bar 40, located a short distance toward the lower end of the chute from a point of mounting of the chute upon the bar 24. Upon the upper side of the lowermost rail of the supporting crane, there is mounted a plate '41, having an upwardly directed sharp-edged flange 42, this plate extending for a distance upon the rail sufficient to enable it to engage the bar 40 with the chute in various positions with respect to the major plane of the frame.

In the use of the device, when material is to be introduced through a window, it may be set up with the frame resting upon the ground immediately in front of the window, and the chute adjusted at the desired slope,

.as indicated in Fig. 2. It will be seen that by drawing the chute outwardly, the rack 40 resting upon the plate 41, it may be presented at a considerable inclination with the lower end of the chute closely adjacent the wall 10 of the building, and the bar 40 will engage the plate 41 at any desired position, to prevent the chute from moving downwardly. The rack bar 40 may also be moved slidably upon the flange 42 of the plate 41 when the chute is to be moved laterally, as will be readily understood.

In Fig. 8 there is shown a construction in which the stiles are provided with longitudinal slots 44 to receive the ends 21 of the crank hanger, suitable apertures being formed in the stiles extending from front to rear, in which a pin 45 may be inserted, to support the crank hanger at any desired height, enabling ready adjustment of the chute, as will be understood. This construction is especially desirable in connection with the use of the clamping screw 33 shown in Fig. 6. Tie rods may be coengaged between the stiles, as indicated at 1618 in Fig. 1, and as shown in Fig. 8 similar rods 17 18" may be located immediately above the mid dle rail 17, and immediately under the top rail 18, upon which a metal sign 46 may be secured by having its edges turned rearwardly around the rods, the sign serving as a shield. As indicated in Fig. 9, the rack element may be connected pivotally to the chute, instead of being fixed rigidly upon the bottom thereof, in this instance being pivotally connected to the eye bolt 35, which is suitably constructed for that purpose, the rack being indicated at 41. The eye bolt 35 is formed with a suitable ear 47 at the lower part, upon which the bar 41. is pivoted, as shown. In this view, also, the chute is shown supported by means of chains 50 at each side, connected to the frame in any suitable way, in the present instance being 7 engaged over a tie rod 17*, located directly under the middle rail 17 of the supporting frame.

In practice, the frameis constructed with the stiles spaced a distance apart approximately the same as the width of theaverage cellar window, and if desired shutters or vanes may be hinged at the sides of the frame, as indicated at 48, in Fig. 1, al- 7 though these may be omitted if desired, as the shield at the upper part of the frame is the most important feature to incorporate,

to protect the building, as will be readily understood by those experienced in the use of such devices.

It may also be found desirable to construct the frame so that it may be supported upon the sill of a window, instead of upon the ground outside thereof, andin Fig. 9 there is shown a frame constructed substantially as before described, upon the stiles of which at their lower part there are secured blocks 49, adapted to extend inwardly from the frame so as to rest upon the sill of a window, as shown. The blocks maybe pivoted or rigidly connected to the frame, as found most desirable, being indicated in the present instance as pivoted, and arranged to strike a check 49 when at the upper inner limit of their movement.

The device is of course readily adapted to be constructed of wood or metal, by methods familiar to workers in various materials, although as shown in the present embodiment the device is particularly adapted to be produced from wood.

What is claimed is:

l. A device of the character described comprising a supporting frame having an opening therethrough, a chute movably connected to the frame and adapted to be extended through the opening at times, a bar toothed on its lower side pivoted on the under side of the chute, and a transverse plate at the lower part of the frame having an upwardly directed edge positioned to engage the bar for the purposes described.

2. A device of the character described comprising a frame having an opening therethrough, a chute having swinging connections with the frame and positioned for sliding movement of its upper end through said opening at times, a ratchet bar connected to the underside of the chute, and a transverse plate carried by the frame at the lower side of the opening having an inwardly extending flange to engage said bar.

3. A device of the character described comprising a frame having an opening therethrough, a horizontal shaft revolubly mounted across the opening, having a crank portion including a horizontal eccentric chute carrying portion, a chute mounted pivotally upon the horizontal eccentric portion for lateral oscillation, and means on the chute and frame to hold the chute against longitudinal movement in the frame at various positions.

4. A portable chute and window guard comprising a frame having an opening therethrough, a chute, a swinging connec tion pivoted on the chute and the frame the said connection having movement in an arc permitting free reciprocation of the chute in the opening, and the chute having one end close enough to the point of attachment thereto of the swinging connection for movement to present its upper end through said opening at times, for movement as described to lie in close parallel relation with and against the frame at other times, and means to secure the chute in position in the opening.

In testimony whereof I have affixed my signature in the presence of tWo witnesses.
